Sunset yellow fcf

Sunset Yellow FCF (CAS 2783-94-0), also known as FD&C Yellow 6, Orange Yellow S, and E110, is a synthetic azo dye that imparts a characteristic orange-yellow hue to food, beverage, and industrial products.

C.I. Food Yellow 3 is the colorimetric designation used in technical and regulatory documentation. It is approved across major regulatory frameworks and widely specified by formulators requiring consistent, heat-stable orange coloration.

In food and beverage manufacturing, E110 is used to color soft drinks, confectionery, snack coatings, and processed foods where a bright orange-yellow appearance is required for consumer appeal.

Pharmaceutical and nutraceutical producers incorporate it into tablet coatings, capsule shells, and liquid preparations to achieve uniform color for product identification and branding purposes.

In the textile and leather industries, it is applied in dyebath processes to achieve orange shades on natural and synthetic substrates. Printing ink formulators also use it as a colorant in packaging inks.

Sunset Yellow FCF is supplied as a fine orange-red powder, typically in sodium salt form. Standard grades include food-grade (FCC), pharmaceutical-grade (USP/BP), and technical-grade for industrial dyeing applications.

Purity specifications for food and pharma grades generally require a minimum dye content of 85%, with low-heavy-metal and low-subsidiary-dye specifications to ensure safety and performance.
